PISTON-ONR-NOAA_RVMirai_2018: Ship-Based Atmospheric and Oceanic Observations

PISTON-ONR-NOAA_RVMirai_2018 contains data from a 2018 collaborative cruise of the Japanese research vessel R/V Mirai in the Philippine Sea. The dataset is part of the multi-agency PISTON field campaign, which deployed three shipboard cruises, eight drifting floats, and two full-depth moorings between August 2018 and September 2019 to study multi-scale tropical convection and air-sea interaction. Its columns likely contain vertical profiles of atmospheric temperature, pressure, winds, water vapor, and precipitation, as suggested by the platform tags.

Use Cases

• Analyzing vertical wind and temperature profiles to study the structure of the Boreal Summer Intraseasonal Oscillation (BSISO).
• Investigating precipitation profiles and water vapor indicators for tropical convection lifecycle studies.
• Validating and improving numerical weather prediction models for the tropical northwestern Pacific region.
• Studying air-sea interaction processes using coordinated ship-based and moored observations.

Strengths

• Data originates from a coordinated, multi-instrument field campaign involving NASA, ONR, and NOAA.
• Campaign deployed multiple platforms including three ship cruises and ten oceanic instruments, providing a multi-faceted observational network.
• Temporal coverage spans over a year (August 2018 - September 2019), capturing seasonal variability.

Limitations

• Key metadata is missing or conflicting: column names and row counts are unknown, and the 'last updated' date differs between sources (2018-09-02 vs. 2026-04-09).
• The specific data format and structure for the R/V Mirai product are not described, complicating direct use.
